Caecilianus

Caecilianus was Bishop of Carthage at the time of the First Council of Nicaea in 325 AD.

Biography
Caecilianus was an archdeacon of Carthage in Libya before becoming its bishop upon the death of Mensurius, and he was known for his superstitious veneration of martyrs' relics. Constantine the Great was disgusted with his petty squabbling over who the rightful bishop of Libya was; in 313 AD, charges against Caecilianus were dismissed at a council in Rome, and his rival Donatus was ruled to have violated the laws of the Christian Church and were forced to rejoin Caecilianus' church if they wished to remain in communion. Constantine ultimately sided with Caecilianus at several councils, but North Africa remained religiously divided.
